Abstract
A polyolefin thermoplastic elastomer composition for an airbag chute, includes a polypropylene, an olefin block copolymer, and a dendrimer as a material applied to a raw material of a passenger airbag chute. An olefin elastomer composite resin composition for an airbag chute includes 30-80 parts by weight of a polypropylene resin, 30-70 parts by weight of an olefin block copolymer, and 0.1-5 parts by weight of a dendrimer based on 100 parts by weight of the olefin elastomer composite resin composition. The olefin elastomer composite resin composition for an airbag chute, improves the dispersion of the elastomer by applying a high-flow elastomer and a low-flow polypropylene, and improves flowability and meltability characteristics without deteriorating physical properties by applying the dendrimer.
